Thanks for your advice. I did feed them till the hive is full then tried to split them previously. However my hives are made of coconut trunk ie fixed and I had to cut the combs to tie onto a movable frame. My modified langstrogh also takes 10 to 11 frames. They just don't seem to like my better hives and prefer the coconut hives. Maybe I made an error by harvesting some honey as I split them. Should I be using smoke? I did not in the previous attempt to split.
Please see this site in Beemaster to look at my setup:http://www.beemaster.com/beebbs/viewtopic.php?t=967
